    This issue of P/PV In Brief focuses on Lauren J. Kotloff's recent report, Leaving the Street: Young Fathers Move from Hustling to Legitimate Work. Based on an in-depth interview study of participants in P/PVs Fathers at Work initiative, the report provides a rare glimpse inside the lives of young urban men with criminal records, exploring how they got involved with hustling, their experiences in the labor market and their feelings about fatherhood.Leaving the Street In Brief describes the four distinct groups that emerged in P/PVs study (the Reluctant Hustlers, the Ambitious Workers, the Reluctant Workers and the Committed Hustlers) and presents early findings from the Fathers at Work evaluation. It also touches on the full report's recommendations for programs serving young fathers

    Crossmodal Attentive Skill Learner

    Full text link
    This paper presents the Crossmodal Attentive Skill Learner (CASL), integrated with the recently-introduced Asynchronous Advantage Option-Critic (A2OC) architecture [Harb et al., 2017] to enable hierarchical reinforcement learning across multiple sensory inputs. We provide concrete examples where the approach not only improves performance in a single task, but accelerates transfer to new tasks. We demonstrate the attention mechanism anticipates and identifies useful latent features, while filtering irrelevant sensor modalities during execution. We modify the Arcade Learning Environment [Bellemare et al., 2013] to support audio queries, and conduct evaluations of crossmodal learning in the Atari 2600 game Amidar. Finally, building on the recent work of Babaeizadeh et al. [2017], we open-source a fast hybrid CPU-GPU implementation of CASL.Comment: International Conference on Autonomous Agents and Multiagent Systems (AAMAS) 2018, NIPS 2017 Deep Reinforcement Learning Symposiu

    Networking Effects on Cooperation in Evolutionary Snowdrift Game

    Full text link
    The effects of networking on the extent of cooperation emerging in a competitive setting are studied. The evolutionary snowdrift game, which represents a realistic alternative to the well-known Prisoner's Dilemma, is studied in the Watts-Strogatz network that spans the regular, small-world, and random networks through random re-wiring. Over a wide range of payoffs, a re-wired network is found to suppress cooperation when compared with a well-mixed or fully connected system. Two extinction payoffs, that characterize the emergence of a homogeneous steady state, are identified. It is found that, unlike in the Prisoner's Dilemma, the standard deviation of the degree distribution is the dominant network property that governs the extinction payoffs.Comment: Changed conten
